Vanadium has a high melting point and is often called a refractory metal with niobium, tantalum, tungsten and molybdenum. It is malleable, hard and non-magnetic. It has the ability to resist hydrochloric acid and sulfuric acid, and the performance of gas resistance, salt resistance and water corrosion resistance is better than most stainless steels. At room temperature, the dense metal vanadium is more stable, does not interact with air, water and alkali, and can also resist dilute vanadium acid, which is a silver-gray metal. Melting point 1890±10℃, belongs to the high melting point of rare metals. Its boiling point is 3380℃, pure vanadium is hard, non-magnetic, and malleable, but if it contains a small amount of impurities, especially nitrogen, oxygen, hydrogen, etc., it can significantly reduce its plasticity.

Uses: Vanadium is a high melting point refractory rare metal, widely used in machinery, automobiles, shipbuilding, railways, batteries, aviation, Bridges, electronic technology, national defense industry and other industries.
